#36 Warnings Not Being Displayed

[robert]

When entering information as an ordinary user, various
mistakes or illegal conditions can occur due to wrong
information being entered. The php code puts warnings
in a variable called $warning[] in the source file
index.php. One example of this is if the user enters a
start-date that is in the past. (around line # 237.
When this happens, the code erases the starttime value,
but the warning text is never displayed. For other
situations, a javascript alert is used, but for this
case, the alert does not seem to be issued. The user
is left confused, not knowing why the date/time he
entered was erased.
